Self-Massage Device
A massage device comprises a body having a body-contacting head adjacent one end and a handle adjacent the other end, the body shaped to permit the user to reach the back of his/her body with the head when the handle is at the user's front or side; and having a rest pivot extending from the body and terminating at a distal end in a support-contacting face, the rest pivot being positioned so that when the device is between a support surface and the user with the head in contact with the user's body and the handle positioned for contact by the user's hand, (a) the user's bodyweight stabilizes the rest pivot against sliding movement on the support and (b) any pivoting force about the rest pivot applied by the user's hand to the handle is substantially less than the force exerted against the user's body by the head.
This invention is directed to a massage device which acts upon a user's body by moving or massaging a portion of the body to produce a therapeutic effect.
BACKGROUNDThis massage apparatus herein is intended to aid in a self-massage of regions of the body which are nearly or completely inaccessible using hands alone by applying pressure to treat sore muscles and trigger points on hard-to-reach areas of the back, neck and shoulders without tiring upper body muscles.
Devices commonly used in self-massaging the back tend to be held in the user's hands and pulled to the place of tension. Examples of such devices are trigger point massage devices such as the “AccuMassager Trigger Point Massager” offered by Body Back Company at www.bodyback.com, the “Backnobber Massager 2” offered by The Pressure Positive at www.backnobber-store.com, the “SoloMAX self-massage tool” offered by Kelly Kinetics, the “Thera Cane” offered by Thera Cane at www.theracane.com, and the “Body Back Buddy Jr. Trigger Point Travel Massager”, the “Body Back Buddy Trigger Point Massager”, and the “Body Back Mini Trigger Point Travel Massager” offered by Body Back at www.bodyback.com.
The massage devices to which the present invention is directed require the user to hold the device over his/her shoulder in order to direct the body-contacting tip of the device to the point of massage, and to then moving the device by pushing, pulling and otherwise manipulating it with his/her arms and shoulders in order to apply pressure to the problem point. Devices of this type are ineffective because the muscles they are designed to help relax are actually involved in the massage process. Also, the arm strength of some users is limited, and they cannot easily and/or comfortably reach the problem spot(s) with the massage device and/or use the device effectively owing to an inability to apply an effective degree of force to the problem spot.
SUMMARYThis invention herein is directed to a massage device that allows the user to relax the back and shoulders while, at the same time, applying sufficient and effective force to the massage point. More specifically, a massage device constructed in accordance with the invention permits the user to apply at least a substantial portion of his/her body weight to the massage point on their back, neck and shoulders. Little arm strength, and the use of only one hand or arm, is required and there is no strain on the upper body.
Briefly, the massage device comprises a main body having a body-contacting head point adjacent one end, a manually grippable handle region adjacent the other end, and a rest pivot extending from the main body that terminates at a distal end in a support-contacting surface for contacting a wall or other supporting structure. The main body is shaped to permit the user to reach the back of his/her body with the head end when the handle region is at the user's front or side. The rest pivot is positioned with respect to the head point so that at least some of a user's bodyweight is applied to the rest pivot when the massage device is sandwiched between the support surface and user, with the head point in contact with the user's body; the rest pivot is positioned on the massage device so that bodyweight applied to the rest pivot generally stabilizes the rest pivot against sliding movement on the support. The rest pivot's position on the massage device provides mechanical advantage whereby any pivoting force applied to the handle region of the main body about the rest pivot is substantially less than the force exerted against the user's body by the head point.
Other details and features of the invention will become apparent from the following detailed description, including the annexed drawings, which discloses a preferred embodiment of the invention.
In the drawing,
As illustrated in FIGS. 1 and 2A-C, a preferred embodiment of the massage device comprises a generally “S”-shaped main body 1 having a body-contacting head point 4 at one end (hereinafter referred to as the “head end”), and a handle region adjacent the other end 5 (hereinafter, the “handle end”). The main body may alternatively be generally “J”-shaped, lacking the curve adjacent said other end 5 and instead extending generally linearly to said other end, without departing from the scope of the invention. In either shape, the main body is shaped to permit the user to reach the back of his body with the head end when the handle region is at the user's front or side.
The main body 1 can formed from a single integral piece of plastic, wood or metal or can be formed from multiple reversibly detachable parts. The preferred main body 1 is bifurcated into two body segments 1a, 1b that are coupled together by a locking mechanism 2 that allows the main body to be taken apart for convenient storage or travel and thereafter securely reassembled. Examples of locking mechanisms are illustrated in
An alternative bifurcated configuration for coupling the two body segments together is illustrated in
As best illustrated in FIGS. 1 and 2A-B, the main body 1 is supported against a wall by a rest pivot 3 that allows the body 1 to swivel and turn without slipping off the wall. The preferred rest pivot 3 includes a base 6 having a wall-contacting face with a wall-contacting surface. The base 6 illustrated in FIGS. 1 and 2A-B is generally cup-shaped, with a wall contacting face that can be generally planar or generally concave (i.e., similar to a suction cup's shape). At least the wall-contacting surface of the base 6 is preferably made from a non-abrasive and/or resilient material: for example, latex rubber, plastic, foam, metal and combinations thereof. The illustrated rest pivot further includes an arm 3a pivotably coupled to the base by a ball and socket mechanism 7, or other pivot mechanism, to enable the body 1 to swivel and turn with respect to the wall-contacting surface.
When the massage device is sandwiched between a support surface (such as the wall illustrated in
A user may alternatively use a chair's back while sitting in the chair, or may use a tree, car, floor or any other suitable surface as a support surface without departing from the scope of the invention.
The rest pivot can be an integral part of the main body 1, or attached to the main body either permanently or detachably. When “integral”, it may formed as part of the main body 1 as, for example, a part of a mold used to make the body. Alternatively, it may be relatively permanently affixed to the main body by mechanical or chemical means in a manner rendering it impractical, unlikely or impossible for a user to remove it.
The preferred rest pivot illustrated in FIGS. 1 and 2A-B includes an arm 3a that can be formed as an integral or detachable part of the main body 1 and can be either permanently or removably attached to the pivot mechanism 7. Alternatively, the main body 1 may include an arm 3a that slides over or into a similar arm extending from the base 6 that is pivotably coupled to the base.
While it is preferred that the pivot arm 3a extend from the main body 1 at a position opposite the head point 4 as illustrated by way of example in FIGS. 1 and 2A-B, the rest pivot can alternatively extend from the main body 1 at a position offset from the head point as, for example, illustrated in
The rest pivot's position can be fixed with respect to the main body 1, as illustrated by way of examples in
As illustrated in
In
In all cases, the use of a non-abrasive support-contacting surface is preferred, and particularly one fabricated from a non-slip material as a precaution. The material may be applied to a hard plastic material or other material lacking the preferred characteristics, as exemplified by the non-slip material 30 affixed to the support-contacting surface of the pivot housing in
The rest pivot can be removably secured to the body, as illustrated by way of example in
The detachable attachment of the rest pivot can alternatively be accomplished by providing the stem 10 and arm 3a with mating threads that enable the rest pivot be screwed into the arm and unscrewed therefrom. Other mechanical couplings can be provided that renders the rest pivot releasably secured within the body 1 as well. For example, a locking mechanism similar to locking mechanism 2 (
The releasably-securing mechanisms described above can also be used at the head point end of the body to provide detachable and/or interchangeable heads points. Changeable head points permit the device's head point to be used for different applications: e.g., as a scratcher, a lotion-applicator, a wash cloth, a brush, etc. As illustrated in
As illustrated in
While designed to be used as a no strain self massager (leaning against a wall, chair back or other supporting surface), the device can also be used like prior art devices wherein the device is pulled to the place of tension without the aid of a wall or base pivot.
Although the present invention and its advantages have been described in detail, it should be understood that various changes, substitutions and alterations can be made herein without departing from the spirit and scope of the invention as will be defined by appended claims.
